SPECIFICATION forming part of Letters Patent No. 242,245, dated Mey 31,1881.

Application tiled February 2, 1881. (Model.)

To all whom fit may concern Be it known that I, ABRAHAM ANDnRsoN, acitizen ofthe United States,resident at Galesburg, in the county ot'Knox and State of Illinois, have invented certain new and usefulImprovements in Windmills; and I do hereby declare the following to be at'ull, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompauyin g drawings, and toletters or igures of reference marked thereon, which form a part ot'this specification, in which- Figure l is a vertical section. Fig. 2 isa detail. Fig. 3 is a top view.V Figs. 4, 5, and 6 are details.

This invention relates to windmills; and it consists in the constructionhereinafter described.

In the drawings hereto annexed, A represents the tower carrying thestructure. Secured to this by bolts passing through lugs b is thesupportin g-plate B, upon which is located the table C.

D is the bot-tom plate of the table, consisting ot' an annulus havinginner iiange, d, with bolt-seats d and tread d2, having the channel d3.

E is an annulus having tlange c, with exterior screw-threaded lugs, e',said liange formin g a rabbet to receive the periphery ofplate D.

Formed upon the inside of annulus E are the tapered studs orjournal-arms e3, these studs and lugs e being at the ends ofright-angled diameters.

Journaled upon studs e3 are the wheels E', whose tread is in channel d.

F is another annulus having flan ges ff, one with bolt-seats f2, theother with turned-up lugs f3 and stud f 4, carrying a roller, F', 011its under side. On its under side,jbetween the iian ges f j" annulus .Fhas the channel f5, concentric with channel d3 of plate D. On its upperside this annulus F has the tread f6.

G is another annulus rabbeted like annulus E, and having tapered studsg, carrying wheels G. Projecting from this annulus is the arm H, havingthe two seats or open sockets h It', with bolt-holes g! g2, and havingthe eye L2 turned to the side from the open sockets.

I is the cover-plate, being an annulus having inner tlange, y, withbolt-seats y and outer flange, y2, and the channel 3/3 between the tlanges. Formed on this annulus is a lug, y, screw-threaded, and on the sameside, but within, a threaded hole, if, is made. To the other side ofthis annulus is placed the lower plate, J, of a bearing.

These plates and annuli, as described, are put together and are held bybolts K passing through the seats on the inside and fastened by nuts.The table is then secured to plate B by bolts L passing through lugs e011 plate E and lugs k2 on plate B. This forms a turn-table capable ofmoving with slight pressure.

The plate J contains the bearing-blocks j j, and has the screw-threadedlugs j j and end openings, j2 jz.

J is the cover-plate, constructed similar to plate J.

L is the spider for carrying the fan-arms, consisting ofthe seats Z, hubl', and journal Z2, passing through hub Z', having the bearingportionsZ4, and carrying the eccentric M, with pin m at its inner end. Securedto this pin m by box a is the pitman N, for connecting with themachinery below.

Ilaced in seats l are the ends p of the arms P, being held therein byplate Q, having seats q, in which the arms partly rest, and nut Q on ping', held in hub l.

Fastened to arlns P are the sailbearing bars R.

r are plates having seats r', in which rest the arms P and outsideseats, r2, in which rest the bars R.

p are outside plates, having seats p2 for the outer edges of bars R torest in, the two plates r and p being held together and to arms P bybolts p3, which pass inside of bars It.

Cut in bars R are the oblique kerfs r3 for the reception of the sailsIt.

Secured to top or cover plate, I, at lugg/4 and hole g5, is a bridge, S,channeled underneath at s, and carrying at each end a pulley, s'. At theouter end of S is the eye s2, in which is the bolt s for the attachmentof joint T, to which is held byboltt and arms t' t the lever U, whoseupper end, u, is journaled to a post,V,by which it is swiveled in eye h2ot' arm H, the other end, u', carrying adjustable weights W.

Runningfrom end a is a cord, X, which passe-Sover pulleys s down intothe tower.

In seats h h the tail is bolted.

IOO

The Weight W regulates the speed by keeping the sails up to the desiredpoint with regard to the wind, and by operating cord X the sails can bethrown out of the wind. The overhanging lips of the various parts of thetable and the closed construction of the bearing for the journal Z2 keepout the Weather. Roller F takes the strain when there is great pressureou the sails.

What I claim is- 1. Plate D, having channel d, annulus E, provided withtapered studs e3, wheels E, annulus F', provided with channel f 5 andtreadf, annulus G, havin g tapered studs g, and wheels ABRAHAM ANDERSON.
